Dear all,
I have started a new RFC with some proposals for the interproject links and
you can add more if you want.
https://meta.wikimedia.org/wiki/Requests_for_comment/Interproject_links_int…
It has been a long standing issue and one of the most voted enhancements in
Bugzilla
https://bugzilla.wikimedia.org/show_bug.cgi?id=708
To have the sister projects templates at the bottom of the page it is also
one of the reasons why sister projects have been also so hidden from the
eyes of the big public, and now with Wikidata also the issue of
maintainability can be addressed as well (similar problem as with
interlanguage links).
